解方程,带※要验算.
1.x+35=79.4
2.x-5.4=0.8
3.x/5=4.26
4.3.6x=9.72
5.※1.5x=4.5
6.※x/0.92=1.5
解方程,带※要验算.1.x+35=79.42.x-5.4=0.83.x/5=4.264.3.6x=9.725.※1.5x=4.56.※x/0.92=1.5
x+35=79.4
X+35-35=79.4-35
X=44.4
x-5.4=0.8
X-5.4+5.4=0.8+5.4
X=6.2
x/5=4.26
X/5x5=4.26x5
X=21.3
3.6x=9.72
3.6X/3.6=9.72/3.6
X=2.6722.
1.5x=4.5
1.5X/1.5=4.5/1.5
X=3
检验:把X=3代入原方程,左边=1.5x3=4.5,右边=4.5,
左边=右边,所以,X=1.5是原方程的解.
x/0.92=1.5
X/0.92x0.92=15x0.92
X=1.38
检验:把X=1.38带入原方程,左边=1.38/0.92=1.5,右边=1.5,
左边=右边,所以,X=1.38是原方程的解.
1)44.4 2)6.2 3)21.3 4)2.7 5)x=4.5/1.5=3 6)X=1.5/0.92=75/46
你五年级吧!!!!!!!!(不许吵哦)
1。×+35=79.4 2.×-5.4=0.8
× =79.4-35 X =0.8+5.4 × =79.4-35
